You're welcome, Pygathrix ...
No, I don't agree-both on the global level aspect (at least partly) as well as on the "condescending" aspect.
"Large tracts of the Amazonian rainforest" have been replaced or destroyed not just by beef ranches, but also due to logging and by farms producing crops like soy beans etc.-and that not just for the animal food market, but also for the "fat behinds" of Americans and Europeans (so other western nations don't have large bottoms?-interesting; so the fat Japanese guys I saw on Sumo-TV are probably Europeans or Americans...

) as well as the ever-growing human population worldwide, in the form of various soy etc. products...
BTW: "In case you hadn't noticed"-whoa, who's condescending whom? Neither did I treat You like an idiot nor did I call You one.
It's not just the western societies that can be addressed as the "prinicipal root of threat"; it's all 6+ billion of us. And due to this, even if the "fat-behinded" Americans and Europeans changed their diet from one day to another, this wouldn't change a lot in terms of "the" rainforest; they or others, like the Chinese, would just use the area for another purpose, may it be soy beans, corn or aquacultures. After all, there are still 6 billion mouths that want to be fed. That's all what my post said-no condescending, no insulting; I'm just not buying the advertisements by the vegans and their kind as there are too many "plot holes" and inconsistencies in their suggestions-that's all.
@NZ Jeremy: "herbivore"? I'd say that the term "omnivore" actually is the best fitting one; we neither have complex and large intestines like many herbivore animals; nor do we have the "equipment" for a carnivorous lifestyle like cats. And if You look at all the things humans eat & drink worldwide-meat,vegetables, roots, fruits, fish, blood, mushrooms, milk & milk products(including "mite" cheese), vegemite, various invertebrates, duck legs, haggis, American hotdogs, kopi luwak, fish eggs, twinkie, Bird's nest soup...then the term "devouring all" is pretty appropriate.
